Wavepacket-Wavepacket Scattering

A simple and explicit technique for the numerical solution of the two-particle, time-dependent Schrvdinger equation is assembled and tested. The technique can handle interparticle potentials that are arbitrary functions of the coordinates of each particle, arbitrary initial and boundary conditions, and multi-dimensional equations. Plots and animations are given here and on the World Wide Web of the scattering of two wavepackets in one dimension.
